pg_exec -- send a command string to the server


pg_exec dbHandle queryString



Specifies a valid database handle.


Specifies a valid SQL query.



A Tcl error will be returned if pgtcl was unable to obtain a backend response. Otherwise, a query result object is created and a handle for it is returned. This handle can be passed to pg_result to obtain the results of the query.


pg_exec submits a query to the PostgreSQL backend and returns a result. Query result handles start with the connection handle and add a period and a result number.

Note that lack of a Tcl error is not proof that the query succeeded! An error message returned by the backend will be processed as a query result with failure status, not by generating a Tcl error in pg_exec.
